Alternatively, a laser device can be used instead of cutting the blade.

In the first optical component layer F1 after the half cutting, the optical module body F1a and the surface protective film F4a are cut in the thickness direction thereof to form a transverse line across the entire width of the first optical component layer F1 in the layer width direction. The first optical component layer F1 is divided into sections having a length corresponding to the short side of the display region P4 in the longitudinal direction by the transverse line. The partitions are each one of the plies (first ply F1m) of the ply F5.

The blade 31c is such that the first optical component layer F1 is wound at its acute angle at its acute angle. When the first optical component layer F1 is folded back at an acute front end of the blade 31c, the separation layer F3a is peeled off from the first layer F1m. At this time, the adhesive layer F2a of the first layer sheet F1m (the bonding surface with the liquid crystal panel P) faces downward. Immediately above the front end portion of the blade 31c is a separation layer peeling position 31e, and the arc-shaped holding surface 32a of the bonding head 32 comes into contact with the front end portion of the blade edge 31c from above, so that the surface protective film F4a of the first layer sheet F1m (and The opposite side of the bonding surface is adhered to the holding surface 32a of the fitting head 32.

The bonding head 32 is parallel to the width direction of the layer, and has a convex arc-shaped holding surface 32a below. The holding surface 32a has a weaker adhesive force than the bonding surface (adhesive layer F2a) of the bonding layer F5, for example, and the surface protective film F4a of the first layer F1m can be repeatedly adhered and peeled off.

The bonding head 32 is formed above the blade 31c and has an axis along the width direction of the layer as a center, and is parallel to the longitudinal direction and is inclined to move along the curved surface of the holding surface 32a. When the first layer sheet F1m is adhered and adhered to the liquid crystal panel P, the tilting movement of the bonding head 32 is appropriately performed.

The bonding head 32 is such that the holding surface 32a faces downward, and the curved one end side (the right side in FIG. 5) of the holding surface 32a is in the inclined state on the lower side, and the curved one end side of the holding surface 32a is attached to the blade edge 31c from above. At the front end portion, the front end portion of the first ply F1m of the separation layer peeling position 31e is adhered to the holding surface 32a. Thereafter, the first layer sheet F1m is taken up and the bonding head 32 is tilted to move, thereby bonding the entire first layer sheet F1m to the holding surface 32a.

The bonding head 32 can perform a lifting operation of a specific distance above the separation layer peeling position 31e and the first bonding position 11c, and can appropriately move between the separation layer peeling position 31e and the first bonding position 11c. The bonding head 32 is coupled to the driving device, and can be driven during the lifting, the moving, and the tilting movement.

When the first layer sheet F1m is adhered to the holding surface 32a, the bonding head 32 is detached from the driving device 33, for example, after the end portion of the first layer sheet F1m is adhered to the holding surface 32a. From this state, the tilting movement is passively accompanied by the unwinding of the first layer sheet F1m. When the bonding head 32 is tilted to move until the first layer F1m is entirely adhered to the holding surface 32a, the tilting movement is locked in the tilted state by, for example, engagement with the driving device 33, and in this state Moves over a fitting position 11c.

When the first layer F1m which is adhered and adhered to the liquid crystal panel P is attached, the bonding head 32 actively moves obliquely by, for example, the driving device 33, and the first layer F1m is attached along the bending of the holding surface 32a. Attached to the upper side of the liquid crystal panel P to be surely bonded.

A first detecting camera 34 is provided below the end portion of the cutting edge 31c, and the leading end in the vicinity of the layer transport downstream side of the bonding layer sheet F5 at the tip end portion of the blade edge 31c is detected. The detection data of the first detection camera 34 is transmitted to the control device 25. When the first detecting camera 34 detects the near end of the downstream side of the bonding layer sheet F5, for example, the control device 25 temporarily stops the layer sheet conveying device 31, and thereafter lowers the bonding head 32 to fix the front end of the bonding layer sheet F5. The portion is adhered to the holding surface 32a.

When the first detecting camera 34 detects the leading end in the vicinity of the downstream side of the bonding layer sheet F5 and temporarily stops the layer sheet conveying device 31, the control device 25 performs the cutting of the bonding layer sheet F5 by the cutting portion 31b. That is, along the detection position of the first detection camera 34 (the optical axis extension position of the first detection camera 34) and the cutting position along the cutting portion 31b (the cutting edge position of the cutting blade of the cutting portion 31b) The distance of the layer transport route corresponds to the length of the layer sheet (first layer sheet F1m) to which the layer sheet F5 is bonded.

The cutting portion 31b is movable along the layer transport path, and the distance between the detection position of the first detecting camera 34 and the cutting position between the cutting positions of the cutting portion 31b is changed by the movement. The movement of the cutting portion 31b is controlled by the transmission control device 25, and after the cutting layer sheet F5 is cut by, for example, the cutting portion 31b, the layer sheet (the first layer sheet F1m) of one bonding layer sheet F5 is wound up. In the case of a distance, when there is a deviation between the cut end and the specific reference position, the deviation is corrected by the movement of the cut portion 31b. Further, the cutting of the bonding layer sheet F5 having a different length may be performed by the movement of the cutting portion 31b.

The first detecting camera 34 can also detect the defect mark printed on the bonding layer F5. This defect mark is marked by the ink jet or the like from the side of the surface protective film F4a when the defect roll is found in the first optical component layer F1 at the time of manufacture of the roll reel R1. The bonding layer sheet F5 (the first layer sheet F1m including the defect) on which the defect mark is detected does not adhere to the liquid crystal panel P after being adhered to the bonding head 32, but moves to avoid the first bonding position 11c. Discard position (discarded position), overlapping to the scrap layer Wait. Further, when the defect mark is detected, the step of cutting off the defective portion including the bonding layer sheet F5 with a minimum width may be designed.

In addition, the defect of the optical component layer FX is, for example, a portion where the solid matter is composed of a foreign matter composed of at least one of a liquid and a gas, or a portion where the surface of the optical component layer FX has irregularities or scratches due to the optical portion. The part of the component layer FX skew or material deviation, etc., which causes bright spots.

When the bonding head 32 moves from the separation layer peeling position 31e toward the first bonding position 11c, it is adhered and held at both corners of the first layer sheet F1m of the holding surface 32a (for example, at the corners of the proximal end portion of the front end portion) Each of the cameras is photographed by a pair of second detecting cameras 35. The detection data of each of the second detecting cameras 35 is transmitted to the control device 25. The control device 25 confirms, for example, the horizontal direction of the first layer sheet F1m with respect to the bonding head 32 based on the photographic data of each of the second detecting cameras 35 (the moving direction of the bonding head 32 and its vertical direction and the direction of rotation of the vertical axis center). )position. In the case where the relative positions of the bonding head 32 and the first layer sheet F1m are different, the bonding head 32 performs position alignment by using the position of the first layer sheet F1m as a specific reference position.

At the first bonding position 11c of the first rotary machine tool 11, a pair of third detecting cameras 36 for performing positional alignment of the liquid crystal panel P in the horizontal direction at the first bonding position 11c are provided. At a second bonding position 11d of the first rotary machine tool 11, a pair of fourth detecting cameras (omitted in the drawings) for performing the horizontal direction of the liquid crystal panel P on the same second bonding position 11d are provided. Position calibration. At a third bonding position 16c of the second rotary machine tool 16, a pair of fifth detecting cameras (omitted in the drawings) for performing the horizontal direction of the liquid crystal panel P on the same third bonding position 16c are provided. Position calibration. The detection data of each detection camera is transmitted to the control device 25). In addition, a sensor can be used instead of each detection camera.

A position alignment table 39 on which the liquid crystal panel P is placed and in which the liquid crystal panel P is horizontally aligned is provided on each of the rotary machine tools (the first rotary machine tool 11 and the second rotary machine tool 16). The position calibration table 39 is driven and controlled by the control device 25 based on the detection data of each detection camera.

Thereby, the liquid crystal panel P with respect to the first rotary machine tool 11 and the second rotary machine tool 16 (the respective bonding positions (the first bonding position 11c, the second bonding position 11d, and the third bonding position 16c) can be performed. Position calibration.

With respect to the liquid crystal panel P, the bonding layer sheet F5 (layer sheet FXm) which has been aligned by the bonding head 32 is bonded to each other, thereby suppressing the misalignment of the optical unit F1X, and the optical component F1X of the liquid crystal panel P can be improved. The accuracy of the optical axis direction improves the color and contrast of the optical display device.

Here, the polarizing film constituting the optical component layer FX is formed, for example, by a polyvinyl alcohol (PVA) film dyed with a dichroic dye toward one axis. There is a case where the thickness of the polyvinyl alcohol (PVA) film is uneven or the dyeing of the dichroic dye is uneven, which may cause a deviation in the optical axis direction in the surface of the optical component layer FX.

In this embodiment, the control device 25 determines the relative optical component layer FX based on the inspection data distributed in the optical axis plane in each portion of the optical component layer FX stored in the storage device 24 (refer to FIG. 1). The bonding position of the liquid crystal panel P (relatively pasting position). Next, each of the bonding apparatuses (the first bonding apparatus 13, the second bonding apparatus 15, and the third bonding apparatus 18) is fitted to the bonding position, and the liquid crystal panel is formed on the layer FXm cut out from the optical component layer FX. Position calibration of P, and the liquid crystal panel P is attached to the layer FXm.

The method of determining the bonding position (relative bonding position) of the layer sheet FXm of the liquid crystal panel P is as follows.

First, as shown in FIG. 6A, a plurality of checkpoints CP in the width direction of the optical component layer FX are set, and the optical axis direction of the optical component layer FX is detected at each checkpoint CP. The time when the optical axis is detected is the time when the roll drum R1 is manufactured, or may be the period before the half of the optical component layer FX is unwound from the roll drum R1. The data in the optical axis direction of the optical component layer FX is stored in the storage device 24 in association with the position of the optical component layer FX (the position in the longitudinal direction and the width direction of the optical component layer FX) (refer to FIG. 1).

The control device 25 acquires the optical axis data (inspection data of the in-plane distribution of the optical axis) of each of the inspection points CP from the storage device 24 to detect the optical component layer FX (which is divided by the transverse line CL) of the portion in which the slice FXm is cut out. The average optical axis direction of the area).

For example, as shown in FIG. 6B, the angle (offset angle) between the optical axis direction and the edge line EL of the optical component layer FX is detected at the checkpoint CP each time, and the maximum angle (maximum offset angle) among the offset angles When θ _max and the minimum angle (minimum offset angle) are taken as θ _min , the average value θ _mid (=(θ _max +θ _min )/2) of the maximum offset angle θ _max and the minimum offset angle θ _min is detected. As the average offset angle. Next, the average offset angle θ _mid direction of the edge line EL with respect to the optical component layer FX is detected as the average optical axis direction of the optical component layer FX. Further, the offset angle is calculated, for example, by a counterclockwise direction with respect to the edge line EL of the optical component layer FX being a positive angle and a clockwise direction being a negative angle.

Next, the bonding position (relative bonding position) of the layer sheet FXm with respect to the liquid crystal panel P is determined according to the average optical axis direction of the optical component layer FX detected by the above method, so that the display area P4 of the liquid crystal panel P is long. The edge or short side is at the target angle. For example, in the case where the optical axis direction of the optical component F1X is set to be 90° with respect to the long side or the short side of the display region P4 according to the design specification, the average optical axis direction of the optical component layer FX is longer than the display region P4. The layer FXm is bonded to the liquid crystal panel P with the side or the short side at 90°.

As shown in FIGS. 7 and 8, the first cutting device 41 and the second cutting device 42 detect the outer peripheral edge of the display region P4 of the liquid crystal panel P by the detecting portions such as the cameras 41a and 42a, along the display region P4. The outer periphery of the liquid crystal panel P is cut off to the layer FXm of the liquid crystal panel P without interruption. The outer periphery of the display region P4 is detected by photographing the end portion of the liquid crystal panel P, the position alignment mark provided on the liquid crystal panel P, or the outermost edge of the black matrix provided in the display region P4.

A frame portion G having a specific width is provided on the outer side of the display region P4 for providing a sealant or the like for bonding the first and second substrates of the liquid crystal panel P to be cut within the width of the frame portion G. The apparatus (the first cutting device 41 and the second cutting device 42) cuts the layer FXm (cut line: WCL, see Fig. 6B).

As described above, the film bonding system 1 according to the first embodiment of the present invention includes a bonding device (the first bonding device 13, the second bonding device 15, and the third bonding device 18). The layer FXm of the optical component layer FX which is larger than the display area P4 of the liquid crystal panel P is attached to the front/rear surface of the liquid crystal panel P, respectively; and the cutting device (the first cutting device 41 and the second cutting device) 42), the remaining portions disposed on the outer side of the opposite portion of the display region P4 are cut from the layers that are respectively bonded to the front/rear surfaces of the liquid crystal panel P, so that the front/rear surfaces of the liquid crystal panel P are respectively formed corresponding to The optical component F1X of the display area P4 size. Therefore, it is possible to design the optical unit F1X to correspond to the display area P4 with better precision, and to reduce the frame portion G outside the display area P4 (refer to FIG. 3), thereby achieving the purpose of expanding the display area and miniaturizing the device.

Further, the film bonding system 1 includes a control device 25 that determines the relative bonding position of the liquid crystal panel P and the layer sheet FXm based on the inspection data of the optical axis direction of the optical component layer FX, and the bonding device (the first bonding device) 13. The second bonding device 15 and the third bonding device 18) are bonded to the liquid crystal panel P by the layer FXm according to the relative bonding position determined by the control device 25. So even in the light In the case where there is a deviation in the direction of the optical axis in the plane of the component layer FX, the relative bonding position of the layer FXm and the liquid crystal panel P can be appropriately adjusted in accordance with the deviation of the optical axis direction. Thereby, the optical axis direction accuracy of the optical component F1X with respect to the liquid crystal panel P can be improved, and the color degree and contrast of the optical display device can be improved.

Further, in the film bonding system 1, the bonding apparatus (the first bonding apparatus 13, the second bonding apparatus 15, and the third bonding apparatus 18) has a winding portion 31a which is optical from the roll drum R1. The component layer FX is unwound together with the separation layer sheet F3a; the cutting portion 31b cuts the optical component layer FX in which the separation layer sheet F3a remains, into a layer sheet FXm; and the blade edge 31c, which is the layer sheet FXm from the separation layer sheet F3a. The bonding head 32 is bonded to the holding surface 32a by bonding the layer sheet FXm, and the layer sheet FXm held by the holding surface 32a is bonded to the liquid crystal panel P. Therefore, the continuous bonding of the layer sheets FXm is facilitated, and the production efficiency of the optical display device can be improved. Further, by using the bonding head 32 having the arc-shaped holding surface 32a, the layer FXm can be smoothly held by the oblique movement of the arc-shaped holding surface 32a, and the same circular arc-shaped holding surface 32a is inclined. The movement can positively bond the layer FXm to the liquid crystal panel P.

Further, in the film bonding system 1, the first cutting device 41 and the second cutting device 42 are laser cutting machines, and the first cutting device 41 and the second cutting device 42 are connected to the same laser output device. 40. The laser system output from the laser output device 40 is branched and supplied to the first cutting device 41 and the second cutting device 42. Therefore, compared with the case where the first cutting device 41 and the second cutting device 42 are respectively connected to the respective laser output devices, the purpose of miniaturizing the production system of the optical display device can be achieved.

(Second embodiment)

Fig. 9A and Fig. 9B are schematic views showing a bonding apparatus suitable for the film bonding system of the second embodiment of the present invention.

Fig. 9A is a schematic view showing a state in which the layer sheet FXm is held by the bonding head 60, and a pattern showing the state in which the layer sheet FXm is bonded to the liquid crystal panel P.

The present embodiment differs from the first embodiment in that the bonding head 32 having the arc-shaped holding surface 32a used in the bonding apparatus of the first embodiment is attached to the embodiment. For the device, a bonding head 60 having a planar holding surface 60a is used. Therefore, the structure of the bonding head 60 will be mainly described here, and structural elements common to the first embodiment will be denoted by the same reference numerals, and detailed description will be omitted.

The bonding apparatus of this embodiment has a bonding head 60, a bonding roller 62, a guide rod 61 that supports the bonding head 60 and the bonding roller 62, and a state in which the guiding rod 61 is tilted relative to the liquid crystal panel P. A drive unit 63 that moves horizontally is performed. Although not shown in the drawings, in the bonding apparatus of the present embodiment, the winding portion, the cutting portion, and the blade (peeling portion) which are the same as those shown in Fig. 5 are provided.

The bonding head 60 has a planar holding surface 60a that holds the layer sheet FXm peeled off from the separation layer sheet. The holding surface 60a is inclined by the guide rod 61 and inclined with respect to the liquid crystal panel P. One end of the layer FXm protrudes outside the holding surface 60a to be positioned to be adsorbed to the holding surface 60a. Since the adsorption force of the layer sheet FXm is weak, the layer sheet FXm can smoothly move in the horizontal direction on the holding surface 60a while being held by the holding surface 60a.

The bonding roller 62 is disposed on the side surface of the bonding head 60, and the liquid crystal panel P is attached thereto and adheres to the layer FXm protruding from the holding surface 60a of the bonding head 60. In this state, when the guide 61 is moved in the horizontal direction by the driving device 63, the bonding head 60 and the bonding roller 62 are separated from the layer FXm in a state where one end of the layer FXm is adhered to the liquid crystal panel P. One of the end sides is horizontally moved toward the other end side. Thereby, the layer sheet FXm is gradually bonded to the liquid crystal panel P from the one end side by the bonding roll 62.

The bonding head 60 is held by the layer FXm of the holding surface 60a, and is aligned by the moving direction of the bonding head in the horizontal direction, the vertical direction thereof, and the rotation direction. Layer FXm and The bonding position (relative bonding position) of the liquid crystal panel P is determined by the control device 25 (refer to FIG. 1) based on the inspection data of the optical axis direction of the optical component layer FX, similarly to the first embodiment. The bonding head 60 is bonded to the liquid crystal panel P by the layer sheet FXm held by the holding surface 60a in accordance with the relative bonding position determined by the control device 25.

Therefore, in the present embodiment, it is possible to provide a production system of an optical display device which displays the frame portion around the reduced area and achieves the expansion of the display area and the miniaturization of the machine.

(first change aspect)

In the above embodiment, a carbon dioxide (CO ₂ ) laser cutting machine is used as an example of the cutting device (the first cutting device 41 and the second cutting device 42), but the cutting device (first cutting) The device 41 and the second cutting device 42) are not limited thereto. Other cutting portions such as a cutting blade may be used as the cutting device (the first cutting device 41 and the second cutting device 42).

For example, as shown in FIG. 10, the three sides of the outer periphery of the first substrate P1 are along the three sides of the corresponding second substrate P2, and the remaining side of the outer periphery is the corresponding second substrate. When one of the sides of P2 extends outward, the size of the second substrate P2 is substantially the same as the size of the display area P4. Therefore, as long as the cutting blade moves along the outer periphery of the second substrate P2, the layer F3m joined to the second substrate P2 can be formed into the optical component F13 corresponding to the size of the display region P4.

In this case, the remaining portion of the layer F3m hardly adheres to the surface of the liquid crystal panel P, and the optical component F13 and the remaining portion of the periphery thereof are roughly bonded only by the adhesive force of the adhesive layer F2a. Therefore, the apparatus for peeling and recovering the remaining portion of the layer sheet F3m from the liquid crystal panel P only needs to be a simple structure in which the end portion of the remaining portion is sandwiched and pulled out, and the apparatus has a simple structure. Further, in the above embodiment, the remaining portions of the plies F1m, F2m and the remaining portions of the ply F3m are peeled off from the liquid crystal panel P by a different mechanism. However, the recycling of the rest of the layer F3m is very easy. Therefore, when the remaining portions of the layer sheets F1m and F2m are peeled off from the liquid crystal panel P, the remaining portion of the layer sheet F3m can be collectively peeled off from the liquid crystal panel P. In this case, since the peeling means of the remaining portion is not required to be provided at two places, the production system of the optical display device can be miniaturized.

(second variation)

In the above-described embodiment, a method of determining the in-plane average optical axis direction of the optical component layer FX is described with respect to the method of determining the bonding position (relative bonding position) of the layer sheet FXm of the liquid crystal panel P. In the foregoing embodiment, in the case where the in-plane maximum offset angle θ _{max of the} optical component layer FX and the average value θ _{mid of the} minimum offset angle θ _min are taken as the average offset angle, the relative optical component layer FX edge is detected. The direction in which the line and the average offset angle θ _mid are sandwiched is the in-plane average optical axis direction of the optical component layer FX, but the method of detecting the in-plane average optical axis direction of the optical component layer FX is not limited thereto.

For example, one or a plurality of checkpoints CP are selected from a plurality of checkpoints CP (refer to FIG. 6A) set in the width direction of the optical component layer FX, and the optical axis direction and the optical are detected for each of the selected checkpoints CP. The angle (offset angle) of the edge line EL of the component layer FX. Then, an average value of the offset angles of the selected one or a plurality of checkpoints CP in the optical axis direction is detected. As the average offset angle, the edge line EL of the optical component layer FX and the average offset angle can also be detected. The direction of the clip is the average optical axis direction of the optical component layer FX.

(third variation)

In the above embodiment, the bonding heads 32 and 60 are used as a method of bonding the layer sheets FXm to the liquid crystal panel P, but the present invention is not limited to this method. It is also possible to use a method in which the layer sheet FXm peeled off from the separation layer sheet F3a by the blade 31c is directly bonded to the liquid crystal panel P by a bonding roll or the like without passing through the bonding heads 32 and 60.

In addition, in the above embodiment of the present invention, the front side of the liquid crystal panel P is explained. The first side and the reverse side are the second side, but the front side of the liquid crystal panel P may be the second side, and the reverse side is the first side.
